Renal Biopsy

Renal biopsy is a procedure used for determining the type of kidney disease by removing a small piece of kidney tissue. It is also known as kidney biopsy. The extracted tissue will be examined under a microscope to look for signs of any damage to the kidneys. 

If your doctor suspects a kidney problem, then he will suggest performing a renal biopsy. A kidney biopsy is also helpful to check how the kidney treatments are working and to know if there are any medical complications after kidney transplantation. A kidney biopsy is performed by inserting a small needle into the skin. Using a small imaging device, the needle will be directed into the kidney to take out kidney tissue.

When Do I Need Renal Biopsy?

A kidney biopsy is used to check what problem is disrupting the regular functioning of your kidneys. Some of the kidney problems can be diagnosed using blood and urine tests without the need for a kidney biopsy. But certain kidney diseases cannot be diagnosed with blood and urine tests and they must need a kidney biopsy for proper diagnosis.

Your doctor might recommend a kidney biopsy to:

  • Determine the reason for the improper functioning of your kidneys
  • Evaluate how well the transplanted kidney is working
  • Determine the cause of blood in the urine (hematuria)
  • Know the reason for proteinuria (protein in urine)
  • Develop a treatment plan for kidney disease
  • Determine the extent of kidney failure 
  • Determine how fast the kidney failure or kidney disease is progressing

Whether you require a kidney biopsy is based on your signs, health condition, and the results of tests. Your doctor will clearly explain why you need a kidney biopsy and its benefits.

How To Prepare for Kidney Biopsy?

Before performing a kidney biopsy, you should discuss with your doctor about what you can expect from the process. You should avoid taking certain medications such as over-the-counter medications, aspirin, and blood-thinning medications. The doctor will explain to you when you should stop taking medications.

The doctor will also collect your blood and urine sample to ensure that you do not have any other infection that can complicate kidney biopsy. You should not drink water or have food for 8 hours before performing a kidney biopsy.

Types of Kidney Biopsy Procedure

During the procedure, you need to lie on your side or abdomen based on which position your doctor will be able to access your kidneys. If you have a transplanted kidney, you need to lie on your back. You will be on IV before beginning the procedure and sedatives may also be given through the IV.

A kidney biopsy can be performed in two ways namely:

  • Percutaneous biopsy: In this method, the doctor inserts a needle into your skin by making a small incision. An ultrasound device is used to guide the needle into your kidney to remove the kidney tissue. Then the needle will be removed and a bandage will be placed on the incision.
  • Open biopsy: If you have any history of bleeding problems, a percutaneous biopsy may not be suitable and open biopsy is used. In this procedure, an operation is performed where a small incision will be made on the skin near the kidney to insert a tube and video camera. The doctor will view your kidney on a screen and remove a sample of kidney tissues.

Recovery After Kidney Biopsy

After the procedure, you will be moved to a recovery room to observe your medical conditions. How long you should stay in the hospital is based on your reaction to the process, and your health condition. During this time, a nurse will keep tracking your blood pressure, pulse, heartbeat, and breathing rate. A blood test and urine test will be conducted to look for any internal bleeding. Once your signs become stable, you can return to your home. 

After going home, you should not lift heavy objects or perform strenuous activities for two weeks. You can eat a normal diet as usual. You may notice blood in your urine for one day after the procedure and it is common. If blood exists in urine for more than one day, you should inform your doctor. The doctor may also prescribe medications to relieve your pain and discomfort.

What To Expect from Kidney Biopsy?

The collected tissue sample will be sent to the lab for examining it. The sample will be analysed under a microscope to look for any abnormal conditions, infections, scars, or any other deposits. If the results show the kidney structure as normal, then you do not need to worry.

If there are any changes in the kidney structure, then the result is considered abnormal. The doctor will discuss the next steps to be taken.
